Abstract

Le couvercle (17) de la zone de travail selon l'invention permet d'obtenir des vitesses de travail et de réglage élevées d'éléments de machines, comme par exemple des chariots mobiles et similaire, dont le dispositif d'entraînement et de guidage est séparé de la zone de travail par le couvercle (17) de la zone de travail. Si des fluides ou particules doivent passer à travers le blindage à lamelles (20), ils seront évacués, de manière contrôlée, par le canal à copeaux (30) ou (33`) prévu séparément. Notamment les copeaux qui atterrissent derrière le blindage à lamelles et sont transportés à l'extrémité fixe de la course du couvercle (17) de la zone de travail par le mouvement de va-et-vient du blindage, sont recueillis par un espace de piégeage (38) et évacués. Cela permet d'éviter efficacement la formation d'amas de copeaux en dehors de l'espace de travail (12) et la diminution de la fonctionnalité de la machine-outil (10).
